Lab: Analysis of Dr. Kitron's Malaria data
Today's lab will be a little different: first, Dr. Kitron will
deliver his lecture (for about an hour). This will be followed by a brief
lab, in which we apply some of the techniques discussed to his data.
Dr. Kitron will either suggest analyses to carry out, or actually
lead them using the projection machine. At this point, the following
possibilities have been suggested:
- Mapping:
- Changing distribution of cases by country of origin over time (e.g.,
Nigeria, India or Guyana).
- Grouping of all cases within a given area (e.g., 25 km2), and then
mapping clusters of cases (e.g. as circles with size related to number of
cases). Maps can then be made for a variety of categories (temporal, origin,
species, etc.).
- Spatial statistics:
- Moran's I for the distribution of cases for the three parasite species.
- k-NN for cases from selected continents or countries.
Here are the details to get you started:
- each of you will receive a diskette
of the data. This is proprietary data, so it is required that you keep it on
the diskette (i.e., do not copy it to any other directory, medium, etc.),
and return the diskette to us when the lab is over.
- On the diskette is a directory, malaria, in which you will find a
project - malaria.apr.
- The project uses some of Esri's data. There are two ways that you can
access this data: you can search for it in the directory structure of your
local computer, or you can download a zipped file
containing the shape files. Unzip it to your hard disk (there's not enough
room on the floppy!).
- Double click on this project. When it asks you for the esri data,
you'll know where to point.
